Remodeling of active endothelial enhancers is associated with aberrant gene-regulatory networks in pulmonary arterial hypertension [RNA-seq]

ABSTRACT: Pulmonary Arterial Hypertension (PAH) is a cardiovascular disease characterized by progressively increasing blood pressure as a result of obliteration and loss of pulmonary arteries. We have extracted pulmonary arterial endothelial cells from lungs of a cohort of PAH patients (n=10) and controls (n=9), cultured the cells for 3-5 passages, and performed chromatin (H3K27ac, H3K4me1, and H3K4me3 ChIP-Seq), expression (RNA-Seq) and chromatin interaction profiling (ChIA-PET). We observed a large-scale remodelling of the active chromatin landscape at enhancers while promoters and gene expression remained unchanged.

Effects of BMPR2 Loss in Human Pulmonary Artery Endothelial Cells

Project description:Pulmonary arterial hypertension (PAH) is a fatal disease characterized by a proliferative endothelial cell phenotype, inflammation and pulmonary vascular remodeling. BMPR2 loss-of-function has been linked to pathologic plexiform lesions with obliteration of distal pulmonary arteries distal pulmonary arteries BMPR2 silencing inprimary human pulmonary artery ECs (HPAECs) recapitulate important aspects of cellular dysfunction and deregulated signaling associated with PAH. Primary HPAECs were transfected with gene-specific siRNA pools targeting BMPR2 or control siRNA followed PMA or control stimulation.

Epigenome-wide profiling uncovers novel pathway networks in human pulmonary arterial hypertension [pul35]

Project description:Pulmonary arterial hypertension (PAH) is a progressive pulmonary vascular disease that culminates in right heart failure. Vascular pathology in PH is characterized by pulmonary vasoconstriction and progressive vascular remodeling processes that affects all layers of the vascular wall (intima, media and adventitia). Our objective was to profile and analyze the differential gene expression signatures between the cells isolated from normal and idiopathic PAH patients. We generated vascular cell-specific transcriptome profiles from the adventitial fibroblasts (PAAF) isolated ex vivo from the dissected human pulmonary arteries of normal donor and PAH lungs using paired-end RNA-sequencing.

Metabolomic heterogeneity of severe pulmonary arterial hypertension

Project description:Although multiple gene and protein expression have been extensively profiled in human pulmonary arterial hypertension (PAH), the mechanism for the development and progression of pulmonary hypertension remains elusive. Analysis of the global metabolomic heterogeneity within the pulmonary vascular system leads to a better understanding of disease progression. Using a combination of high-throughput liquid-and-gas-chromatography-based mass spectrometry, we showed unbiased metabolomic profiles of disrupted glycolysis, increased TCA cycle, and fatty acid metabolites with altered oxidation pathways in the severe human PAH lung. The results suggest that PAH has specific metabolic pathways contributing to increased ATP synthesis for the vascular remodeling process in severe pulmonary hypertension. These identified metabolites may serve as potential biomarkers for the diagnosis of severe PAH. By profiling metabolomic alterations of the PAH lung, we reveal new pathogenic mechanisms of PAH in its later stage, which may differ from the earlier stage of PAH, opening an avenue of exploration for therapeutics that target metabolic pathway alterations in the progression of PAH. Global profiles were determined in human lung tissue and compared across 11 normal and 12 severe pulmonary arterial hypertension patients. Using a combination of microarray and high-throughput liquid-and-gas-chromatography-based mass spectrometry, we showed unbiased metabolomic profiles of disrupted glycolysis, increased TCA cycle, and fatty acid metabolites with altered oxidation pathways in the severe human PAH lung.
